Overview

The LM2902DR is a quad-channel, general-purpose operational amplifier designed for high-voltage operation up to 36V. It features four independent amplifiers in a single 14-SOIC package, offering a wide operating temperature range of -40C to 125C. This component is optimized for cost-sensitive applications requiring multiple gain stages or signal conditioning blocks on a single rail.

Why Choose This Part

The device features integrated RF and EMI filters to enhance robustness in electrically noisy environments. It supports a wide supply range from 3V to 36V with a low input bias current of 20nA, making it versatile for both low-voltage logic and higher voltage industrial rails.

Applications

Transducer Amplifiers
Interfacing with low-frequency industrial sensors to scale and filter analog signals before ADC conversion.
Integrator Circuits
Utilizing multiple channels to create multi-stage active filters or timing circuits in control systems.
DC Gain Blocks
Providing stable gain for DC signals in power supply monitoring and battery management feedback loops.
Signal Summing
Combining multiple analog inputs into a single output stream for mixed-signal processing.

Getting Started

Engineers can prototype with the LM2902DR by using a SOIC-14 to DIP adapter on a standard breadboard or by integrating it into a custom PCB design. Ensure decoupling capacitors are placed close to the VCC pin (up to 36V) and verify that the 1.2 MHz gain bandwidth product meets the requirements of your specific signal frequency.
